I want to start learning an instrument but because I live far from my country I'm looking for self-study.
I'm choosing between my national instruments (Iranian), which some like Oud or Kamancheh are fretless and some like Tar and Setar are fretted.
I like Oud myself but I'm afraid self-teaching a fretless instrument would be hard.
How different are they when it comes to self-learning?
